I know it can be expensive to buy drinks in a restaurant in Japan but I can still get surprised.  On Saturday I went out for pizza in Akihabara.  I decided to order some cola as I was tired and thought that maybe the caffeine would perk me up.   The drink I got was in a small glass, probably around 200 mls, and it cost 400 円 ($5 USD, £3.20 GBP).  It was ridiculous.  I knew how much the drink would cost before I bought it but I wasn’t expecting it to be so small.  My friend ordered a glass of white wine.  He got about the same amount of wine and it was cheaper than my soft drink.  Next time I’ll stick to drinking tap water.
